Missions

Missions orchestrate multi-agent task execution: a LEAD agent plans a breakdown, agents work tasks, and the mission moves through a status flow from PLANNING to a terminal state. Beyond CRUD, the API exposes lifecycle actions — start, restart, resume, and clone — plus task management, mission checkpoints, and workspace-wide metrics.

All mission endpoints require authentication and workspace context.

Status	Condition
`404`	Mission not found

Update Mission

PATCH /api/v1/crews/{crewId}/missions/{missionId}?workspace_id={workspaceId}

Auth: OWNER, ADMIN, or MANAGER role Request Body: All fields optional.

Field	Type	Description
`title`	string	Mission title
`description`	string	Mission description
`plan`	string	Mission plan (markdown)
`status`	string	New status (must be a valid transition)

Status Transitions:

From	Allowed To
`PLANNING`	`IN_PROGRESS`, `CANCELLED`
`IN_PROGRESS`	`REVIEW`, `FAILED`, `CANCELLED`
`REVIEW`	`COMPLETED`, `IN_PROGRESS`, `FAILED`, `CANCELLED`

When status changes to COMPLETED, FAILED, or CANCELLED, completed_at is automatically set. Response: 200 OK — updated mission object.

Status	Condition
`400`	Invalid status transition
`404`	Mission not found

Delete Mission

DELETE /api/v1/crews/{crewId}/missions/{missionId}?workspace_id={workspaceId}

Only missions in PLANNING or CANCELLED status can be deleted (hard delete).

Request: crewId and missionId are required path parameters; workspace_id selects the workspace. No request body. Auth: OWNER, ADMIN, or MANAGER role Response: 204 No Content

Status	Condition
`400`	Mission is not in PLANNING or CANCELLED status
`404`	Mission not found

Lifecycle Actions

Drive a mission through execution: start a planned mission, or restart, resume, and clone existing ones. All require OWNER, ADMIN, or MANAGER role.

Start Mission

POST /api/v1/crews/{crewId}/missions/{missionId}/start?workspace_id={workspaceId}

Transitions a PLANNING mission to IN_PROGRESS and starts the MissionEngine. Validates the task dependency DAG before starting. Uses atomic compare-and-swap to prevent concurrent start races. Auth: OWNER, ADMIN, or MANAGER role Response: 200 OK

{
  "id": "mission_abc",
  "status": "IN_PROGRESS"
}

Status	Condition
`400`	Mission not in PLANNING state, or invalid task DAG
`404`	Mission not found
`409`	Mission was already started by another request
`500`	MissionEngine failed to start (rolls back to PLANNING)

Restart Mission

POST /api/v1/crews/{crewId}/missions/{missionId}/restart?workspace_id={workspaceId}

Restarts a COMPLETED, FAILED, or CANCELLED mission. Resets non-COMPLETED tasks (PENDING if dependencies allow, BLOCKED otherwise), increments their iteration, clears errors, and moves the mission back to PLANNING (call start afterwards to dispatch). (internal/api/task_state.go:14) Request: crewId and missionId are required path parameters; workspace_id selects the workspace. No request body. Auth: OWNER, ADMIN, or MANAGER role Response: 200 OK

{ "id": "mission_abc", "status": "PLANNING" }

Status	Condition
`404`	Mission not found
`409`	Mission is not in a terminal state (`COMPLETED`/`FAILED`/`CANCELLED`)

Resume Mission

POST /api/v1/crews/{crewId}/missions/{missionId}/resume?workspace_id={workspaceId}

Resumes a FAILED mission from the point of failure. The handler atomically claims the mission into RESUMING, resets the FAILED/AWAITING_APPROVAL tasks plus their downstream dependents, validates the DAG, and re-engages the MissionEngine. COMPLETED tasks are preserved. (internal/api/task_state.go:103) Request: crewId and missionId are required path parameters; workspace_id selects the workspace. No request body. Auth: OWNER, ADMIN, or MANAGER role Response: 200 OK

Status	Condition
`400`	No failed tasks to resume from, or invalid DAG
`404`	Mission not found
`409`	Mission is not currently `FAILED`

Clone Mission

POST /api/v1/crews/{crewId}/missions/{missionId}/clone?workspace_id={workspaceId}

Creates a copy of the mission with all its tasks, resetting statuses to PLANNING/PENDING (or BLOCKED if the cloned task carries dependencies). Request: crewId and missionId are required path parameters; workspace_id selects the workspace. No request body. Auth: OWNER, ADMIN, or MANAGER role Response: 201 Created

{ "id": "mission_new", "status": "PLANNING" }

The handler returns the new mission id and status only; fetch GET /api/v1/crews/{crewId}/missions/{newId} for the full mission object (internal/api/task_state.go:472).

Tasks

Add and update the individual tasks that make up a mission’s work breakdown.

Create Task

POST /api/v1/crews/{crewId}/missions/{missionId}/tasks?workspace_id={workspaceId}

Add a task to a mission. Auth: OWNER, ADMIN, or MANAGER role Request Body: (internal/api/task_handler.go:42)

Field	Type	Required	Default	Description
`title`	string	Yes	—	Task title
`description`	string	No	`null`	Task description
`assigned_agent_id`	string	No	`null`	Agent to assign to
`task_order`	integer	No	`0`	Position in task list
`depends_on`	string[]	No	`[]`	Array of task IDs this depends on
`max_iterations`	integer	No	`null`	Max retry iterations

Tasks can only be added to missions in PLANNING or IN_PROGRESS state. If any dependency task is not COMPLETED, the new task is created with status BLOCKED; otherwise PENDING. Response: 201 Created

Update Task

PATCH /api/v1/crews/{crewId}/missions/{missionId}/tasks/{taskId}?workspace_id={workspaceId}

Auth: Authenticated workspace caller with the mission write permission (OWNER, ADMIN, or MANAGER). Request: crewId, missionId, and taskId path parameters, optional workspace_id, and a JSON body containing any of the optional fields below. Response: the updated task object. Statuses: 200 OK; 400 for an invalid transition or body, 403 for insufficient role, 404 when the mission or task is not in the workspace, and 500 for a persistence failure. Request Body: All fields optional. (internal/api/task_handler.go:160 — updateTaskRequest)

Field	Type	Description
`title`	string	Task title (PENDING/BLOCKED only)
`description`	string	Task description (PENDING/BLOCKED only)
`assigned_agent_id`	string	Reassign to a different agent
`status`	string	New status (valid transition required)
`depends_on`	string	JSON-encoded dependency task IDs (PENDING/BLOCKED only)
`result_summary`	string	Result summary text
`error_message`	string	Error message text
`output_path`	string	Output file path
`token_count`	integer	Token usage
`estimated_cost`	number	Estimated cost in USD
`max_iterations`	integer	Max retry iterations (0–`maxTaskIterations`)

status and depends_on cannot be set in the same request — the handler returns 400 with “Cannot update status and depends_on in the same request” (internal/api/task_handler.go:382). task_order and approval_required are not currently mutable through this endpoint. Task Status Transitions:

From	Allowed To
`PENDING`	`IN_PROGRESS`, `SKIPPED`
`BLOCKED`	`PENDING`, `SKIPPED`
`IN_PROGRESS`	`COMPLETED`, `FAILED`, `SKIPPED`

Response: 200 OK

Checkpoints

Cartographer checkpoints bookmark a mission’s journal cursor and state snapshot for the timeline UI. Cartographer checkpoints capture a mission’s journal cursor plus a state snapshot (agent-memory hashes, pending tasks, open assignments, crew container id) so the timeline UI can offer “list bookmarks” and (advisory) “restore/fork from here” affordances. The full restore/fork/get/delete surface is documented on the Checkpoints page; the two endpoints below are mission-scoped and live here for convenience. (internal/api/cartographer_handler.go)

List Mission Checkpoints

GET /api/v1/missions/{missionId}/checkpoints?limit=50

Returns newest-first checkpoints for a mission. Cross-workspace IDs are folded into the same 404 shape as “mission not found” so existence isn’t leaked. Query Parameters:

Parameter	Type	Default	Description
`limit`	integer	`50`	1-200. Values outside the range fall back to the default.

Response: 200 OK

{
  "mission_id": "mission_abc",
  "count": 1,
  "checkpoints": [
    {
      "id": "chk_01h9z7k0",
      "workspace_id": "ws_123",
      "crew_id": "crew_456",
      "mission_id": "mission_abc",
      "label": "green build",
      "journal_cursor": "j_7f3e2a1b8c9d0e12",
      "state": {
        "agent_memory": { "backend-dev": "sha256:…" },
        "pending_tasks": ["task_1"],
        "open_assignments": [],
        "crew_container_id": "crew_456-runner"
      },
      "created_by": "user_5",
      "created_at": "2026-05-14T09:12:44Z"
    }
  ]
}

Status	Condition
`400`	Missing `missionId` path value
`401`	No workspace context on the request
`404`	Mission not in caller’s workspace

Create Mission Checkpoint

POST /api/v1/missions/{missionId}/checkpoints

Captures the mission’s current journal cursor + materialized state and writes a checkpoint row. Body is optional — an unlabelled checkpoint is a valid “bookmark right now” gesture. (internal/api/cartographer_handler.go:91) Request Body: (optional)

Field	Type	Required	Description
`label`	string	No	Human-readable label for the timeline UI

{ "label": "green build" }

Response: 201 Created — full checkpoint object (same shape as the List array entries above). When the row was committed but the immediate re-read failed, the response degrades to { "id": "chk_..." } so the client can still navigate to it.

Status	Condition
`400`	Missing `missionId`, or invalid JSON body
`401`	No workspace context on the request
`404`	Mission not in caller’s workspace
`409`	Mission has no journal entries to anchor a checkpoint against

Metrics

Workspace-wide aggregates for dashboards.

Mission Metrics

GET /api/v1/mission-metrics?workspace_id={workspaceId}

Auth: Authenticated workspace request. Request: required workspace_id query parameter; no body. Response: JSON aggregate metrics object. Statuses: 200 OK; 400 for missing or invalid workspace context, 401 when unauthenticated, and 500 for an aggregation failure. Aggregated mission metrics for the workspace. total_missions and active_missions are lifetime counts; the *_24h fields cover the trailing 24 hours. Response: 200 OK

{
  "total_missions": 45,
  "active_missions": 3,
  "completed_24h": 8,
  "failed_24h": 1,
  "total_tokens_24h": 125000,
  "total_cost_24h": 3.75,
  "avg_completion_time_ms": 180000,
